板式蒸发器过热度的控制方法实验研究
摘要
针对200℃以下的低温热源
选择低沸点有机工质R600a作为余热发电系统的循环工质
搭建了由有机工质R600a和板式蒸发器组成的系统。首先通过理论分析了板式蒸发器的稳态数学模型
为实验和数据的分析提供必要的理论基础。在实验中
改变有机工质R600a的流量测量不同值时实验系统过热度的动态响应
最后确定系统过热度和板式蒸发器的基本传递函数关系。
Abstract
Aimed at source below 200 ℃
organic refrigeration R600a was selected as the working fliud
and the system was built by organic medium R600a and plate evaporator. The paper firstly theoretical analysis the steady state mathematical of plate evaporator
which provides the necessary theoretical foundation for the experiment and data analysis. In the experiment
the different value of overheat was measured when the system changes the flow rate of the R600a refrigerants
and the paper finally confirms the basic transfer function relationship of the type evaporator and the overheat.
